<P>In the next dialogbox the parameters for a QUAD flatpack geometry can be entered. The QUAD flatpack geometry is a SMD based device.</P>

<P>The following parameters can be changed:</P>

<P><U>Nr pins X,Nr pins Y</U></P>

<P>If the total amount of pins is two times the (Nr pins X + Nr pins Y) entered. The pinnumber counting starts with an optional string and a number. and increments with one for the following pins. The pin counting direction is counter clockwise.</P>

<P><U>Pad size X,Y</U></P>

<P><U>Pitch</U></P>

<P><U>Pad size solder mask</U></P>

<P>If the solder mask pad is not necessary, fill one of the parameters (X,Y) with zero.</P>

<P><U>Pad size paste mask</U></P>

<P>If the paste mask pad is not necessary, fill one of the parameters (X,Y) with zero.</P>

<P><U>Clearance</U></P>

<P>The initial clearance is the clearance used for this geometry.</P>

<P><U>Distance X,Y</U></P>

<P><U>Starting pin nr</U></P>

<P>The starting pin nr consists of two editboxes. The first editbox(optional) contains text or a number, and will not be changed. The second editbox contains a start number. This startnumber will be increased with one for the next pads.</P>

<P>The <B>Use default rules for solder paste/mask and clearance</B> button can be used the fill in values based on the pad size.</P>
